the output of the Diagonal matrix of singular values is empty

Hi Jacob Gildenblat,
Thank you for your repo! I think your work is beautiful!
Now, I encounter a problem with the code.
When I run the EVBMF function, the output of the Diagonal matrix of singular values is empty.
So How should I solve this problem?
In addition, Then I rewrite the code from "sigma2 = sigma2_opt.x" to "sigma2 = sigma2_opt.x *0.5", and It works.
Do you think the change of the code like this is right? or does it make sense?
I am looking forward to your reply, thanks!

Hi, I wonder the rewriten code is right? It is because I've met the same question.
